A system and method for management and processing of resource requests is provided. A content delivery network service provider receives a DNS query from a client computing device. The DNS query corresponds to a requested resource from the client computing device. The content delivery network service provider associates the client computing device with a cluster of other client computing devices. Based on routing information for the cluster, the content delivery network service provider routes the DNS query. The process can further include monitoring performance data associated with the delivery of the requested resource and updating the routing information for the cluster based on the performance data for use in processing subsequent requests from client computing devices in the cluster.

11. The system as recited in claim 9, wherein the class is identified in a DNS portion of the URL.
16. The system as recited in claim 15, wherein the class is associated with a plurality of alternative resource identifiers each having a probability of selection for the class.
18. The system as recited in claim 17, wherein determining an alternative URL of the CDN service based on the class comprises determining an alternative URL based on probabilities of selection of alternative resource identifiers for the class.
19. The system as recited in claim 17, wherein determining an alternative URL of the CDN service based on the class comprises determining an alternative URL based on a probability of selection of the URL for the class.
20. The system as recited in claim 17, wherein determining an alternative URL of the CDN service based on the class comprises determining an alternative URL based on a probability of selection for each alternative URL identified in routing information for the class.
